switchport mode trunk
Hi,
sometimes the desired portconfig for a trunk is “it should never become an access port”. Because the port is normaly in ” switchport mode dynamic desirable”
Then i think it’s ok to configuere “switchport mode trunk”. But besides this, are there other reasons to configure “switchport mode trunk”?
As you can see the trunk is operational.
